Answer

What is Rotenone?
Rotenone is a naturally occurring chemical compound that is primarily known for its insecticidal properties. It is derived from the roots of certain plants, particularly those from the family Fabaceae, which includes the Derris and Lonchocarpus species.
Key Characteristics of Rotenone
- Natural Insecticide:
Rotenone is classified as a natural insecticide because it is derived from plant sources, making it more environmentally friendly compared to synthetic pesticides. It disrupts the cellular respiration in insects, leading to their demise.
- Mechanism of Action:
Rotenone inhibits the mitochondrial electron transport chain, specifically affecting complex I. This action prevents insects from utilizing oxygen, effectively suffocating them.
- Broad-Spectrum Activity:
It is effective against a wide range of pests, including aphids, beetles, and caterpillars. This broad-spectrum efficacy makes it a popular choice in organic farming.
Applications of Rotenone
- Agricultural Use:
Farmers use rotenone to protect crops from insect infestations, particularly in organic farming. It allows for pest control without the adverse effects associated with synthetic chemicals.
- Aquaculture:
Rotenone is also utilized in fish management practices. It can be employed to eliminate unwanted fish species from lakes and ponds, allowing for the restoration of native fish populations.
Conclusion
In summary, the correct answer is option 'C' because rotenone is a natural insecticide. Its effectiveness, coupled with its origins from plant sources, makes it a valuable tool in both agriculture and environmental management, distinguishing it from other categories such as herbicides or hormones.
